Isla Chepillo - surf spot statistics

Isla Chepillo in Panama experiences consistent ground swell throughout the year, with the highest probability occurring from April to May (68-72%) and August (67%). The swell is predominantly ground-driven, with minimal wind swell influence, ensuring cleaner wave conditions. However, the mean swell size remains modest at around 0.5-0.6 meters, indicating mostly small to medium waves. Wind conditions are challenging year-round, with the highest likelihood of favorable winds occurring in April (29% good conditions) and the lowest in January-February (14-16%). Despite this, strong onshore winds (bad conditions) dominate, averaging 71-86% probability across all months, peaking in January-February. The best months for surfing are likely April and May due to the highest ground swell consistency and slightly better wind chances (27-29% favorable), though surfers should expect frequent wind interference. Late-year months like November and December see a drop in ground swell (51-57%) and persistent poor winds, making them less ideal. Overall, Isla Chepillo is a spot with reliable but small swells, best surfed in mid-year months when ground swell peaks and wind conditions are marginally better, though wind remains a limiting factor.

In September, Isla Chepillo offers relatively small but clean swells, averaging 0.6m with a decent period of 14.1s, indicating well-spaced, organized waves that can hold shape despite their modest size. The swell direction is predominantly from the S and SSW, with the most consistent wave heights in the 0.5–1m range (42.73% and 22.97%, respectively), occasionally reaching 1–1.5m but rarely larger. Wind conditions are variable, with only 21% of days providing ideal offshore or light cross-shore winds for surfing. The dominant winds come from the S and SSW, often blowing in the 10–20kph range, which can create choppy conditions unless the wind shifts favorably. While the swell size is small for advanced surfers, the long period and clean energy make it suitable for logging or smaller boards when winds align. Expect mostly waist-high waves with occasional chest-high sets, best on days with lighter winds from the northern quadrants. It’s not a high-performance month, but it can be fun for relaxed surfing if timed right.
